Keychain MEGA Micro Bit Kit (pt 3)

hello in my last video I showed how to make sort of a keychain screwdriver that I made from a pens screwdriver takes the 4 millimeter standard so you can have different bits any can either store a bit in it or just a la carte it's super tiny super lightweight it's about a third of the length of my pinky to give me an idea of its size it can detach from your keychain with this quick release mount so you can use it all by itself or just leave it on your keys permanently in this video I'm gonna talk about the matching bit kit for it and my design goals and making a sort of perfect keychain screwdriver here's an idea of the scale the size roughly about the size of a Sharpie pen cap just a little bit longer I've also made it so that it'll fit in and out which in the short dimension which I usually I just wanted to point out that you can take three four millimeter bits put them in the cap and carry three bits that way so that might be a very compact sort of lightweight method as you see this whole device is shorter than my pinky they sort of all-in-one keychain tools such as this bling Victorinox knife that I made in a recent video it's kind of nice nice tools they're pretty durable too but if you do mangle one your entire tool is shot and that's the advantage to using interchangeable bits or this Leatherman micro micro that I made after watching a video by Noah Spurrier on Instructables if one of these screwdriver tips gets mangled your entire product is shot so having interchangeable bits is definitely preferable one very important goal for me is that the product is very lightweight and this registers to grams compare that to a small bit holding screwdriver made by Cobalt this one weighs thirty point seven grams thirty point six grams so obviously this is the clear winner for weight the bits for my design should either store inside the screwdriver this holds about twelve bits for instance not organized though or be connected in some sort of a tethered collection this is a little bit kit that came at the precision screwdriver and I made this kit out of the blister pack material that came with the presentation box this is the Cal Hawk 6 in-1 precision screwdriver that I used to make this about two of them and I just used my razor knife that I keep on my keychain in my tap knife that I've shrunk down and I cut out this container put a squash clamp around it and that's how I made this little bit kit although it's better than nothing happening the bit sort of rattle around in a chamber less than ideal I get disorganized there's no organization to it I showed this little outwards kit with a squash clamps though they don't fall out ideally they should have some organization rather than just rattle in there Loosli so the bit positions aren't labeled there's not that much organization you can sort of see what the tips are but I prefer ideally to have some kind of a labeling mechanism or able to see the side of the bits of the bits themselves have labels there's an example where all the bits have a labeled position I kind of like that I prefer to stick with either four millimeter bits or standard quarter-inch bits they're much easier to find in case you lose one or if you mangle one to buy a replacement bit for your kit some bits are kind of interesting like this Leatherman flat bit it's semi compatible with the full-size standard for instance they make this adapter so you can then use normal full sized bits that's nice very important to me is how small and compact it is and how it attaches to your gear I have to have a keychain attachment on whatever kind of a kit I'm gonna make such as I show on the chapstick kit in the other video and you see all these precision screwdrivers kind of commando style screwdrivers they all may look initially the same right actually not of all of these only one of them this one will fit in an Altoids tin and for me that's really important I definitely prefer bit kits that are clearer so you can sort of see all the tools at once without even having to open it up another advantage to kits that are made of bits is you can select what selection of bits you want to carry on you for instance I have very little need for Phillips number three they fix mostly electronics so I care about Phillips number two and smaller but when you have a kit mate with bits you get to pick what bits you carry on you yourself this has a clip on it and that things you can use this as a dangler let you hang your keys from your pocket edge when you put your keys in your pocket and you attach the clip to the outside so now your keys dangle nicely in your pocket without causing a big bunch up a big bulge so it's both a dangler and a screwdriver so this turned out really nicely I'm really impressed with what this would do but what if you need more than just three bits certainly kind of nice that this is nice and small carries three bits we won't have any problem carrying this around on my keys I don't mind its weight or size but how many bits to carry only three bits in the cap may not be enough be nice to carry a whole kit like one of these clear kits this holds for instance eight bits here's a much bulkier one well it's 2023 bits I like this one that carries 30 bits they're labeled too I always prefer these clear cases this one's quite nice this carries 32 bits but obviously you're not going to carry that on your keychain so how can I carry a big amount of bits would you believe what I'm holding in my hand has 46 bits Dada here is my mega micro bit holder it's made out of a tic tac box not the full size tic tac box it's a smaller tic tac box this is one of their sort of mini cases if you compare it to a full-size tic tac box you see it's quite a bit smaller it's about the size of a 9-volt battery just a little bit longer than a 9-volt battery it's a little bit skinnier than a 9 9 volt guy so let's open this up and show you what's what's inside let me detach the screwdriver first this is a very tight fit by the way this attachment to the keys this has a squash clamp on it so if I drop it it won't bust open squash clamp is just a strap of clear plastic tape although it stays pretty shut just all by itself thanks to the snap in lock on the on the top here but now that I've removed that I can actually open it up this is the opening handle you pull on this first thing we get is a pull-tab this is just made out of the opening part of a roll of clear tape came from this transparent tape this is a we ha microbe jet holder it's called the 75 802 let's me use any of these little micro bits in a full-size screwdriver so for instance I showed how to make this in another video if I want to use any of these micro bits inside this or any other full-sized bit screwdriver I have this on hand which is nice that actually serves multi functions so hopefully my camera angle is good now you can see everything in it's in focus it's a clear case you can actually see the names of the bits through the clear case which is nice we have a lot of bits in there as I said made out of a tic-tac box and the final production unit I'll peel off that sticker but I left that on so you could sort of see what it's what it's made out of now let's extract it so the first thing you do is take off the lid remove the 75080 to whee-ha micro better tap holder you then pull the pull tab and here's the kit - made out of two different kinds of bits a double-sided bits on the top single sided it's at the bottom and if you're wondering why it's because these little boxes they're trapezoidal they're not rectangular so you can only fit double-sided mitts about halfway then you have to do the balance in single sided bits but here's the case you have let's see 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 double-sided bits 14 single sided bits plus you have a double-sided bit here so you have a total of 46 bits this also acts actually is a 4 millimeter hex wrench so that's kind of 47 bits and this not only lets you use it in full-size tools this adapter so you can use these micro bits and full-size quarter inch drive this is also thanks to its magnet is your extraction tool and that's how you extract the individual bits so here's a Phillips Phillips number 2 even though these are micro bits they do go up to Philips number 2 which is nice that covers all my needs so obviously this kit is not going to be good if you're doing like small engine repair or giant machinery but for electronics which is my application this should work fine so despite being so small this is actually incredibly quick and easy to use you open the lid take out the combination extraction tool and full size micro bit conversion you pull out the kit you find the particular bit that you want this has a magnet in it so that when you stick it down it actually grabs onto the bit that you want to help extract it we now insert it into the tool and let's give this a go so I bet a lot of people are thinking pull screwdrivers like that aren't gonna cover full-sized jobs you really want full size bits for that kind of application by the way these bits do fit these little tic-tac boxes quite nicely it can hold about 12 inside however I'm going to show you that even this micro bit category can handle most of my job jobs in my home fact there's not a single device I have with a larger than Phillips number two screwdriver let me show you what this little teeny guy can do you can use the empty tic-tac boxes your screw screw holder by the way suppose that I should give them wider angle so even full-size repairs can be done next to this little teeny micro big screwdriver the quick method you push with one hand and you rotate with the other two fingers I forgot to mention I just made this internal kit by cutting the plastic of a food container by the supermarket or Trader Joe's places like that that just put it together folded it together put some tape on it very simple design but it's clear so you can see the actual bits which I really like see what all the tips are even while it's inside the plastic tic-tac box so if we want to travel light just carry the screwdriver by itself with one bit in place a double-sided bit that'll give you two bits that would be good if you just need like a screwdriver for your eyeglasses so that's the sort of the lightweight method if you want to be able to carry it as a dangler you can also use the clip at the top as a bit holder this will hold up to three bits so that gives you a little more if you want a little more print more bit selection you could use the chap stick modification that I showed in my chapstick duct-tape video this holds the 4 millimeter bits double-sided long so you have a six different double-sided bits and it's stealth so if you're on a stealth spy mission no one's going to know that this is a screwdriver kit originally made for duct tape but works great for this application I've reinforced the clip at the top so that won't bust open but just by putting some extra clear tape to give it more friction so the single bit double-sided bit three bits in the cap twelve bits if you carry this and a grand total of 46 different bit options if you carry a double-sided bit in the main body and the extra tick-tack box oh and keep in mind if you do if you're thinking about doing this you actually can make two of them because the pen that you use you cut it down this is full length before I sawed it off so you'll have two of these so you can keep one on your keychain and keep one in your micro survival kit two for the price of one okay task complete so here's how you put everything away you put the bit that you use back in with the name facing outward you slide this into the case you put the whee-ha adapter right there have a nice tight fit doesn't tend to open all by itself but for extra security we do want to put on the external strap what I call a squash clamp made a few of these this is how you have 46 bits on your keychain for very little money and quite easy to make you so I call this a 46 in one screwdriver you can actually kind of sneakily make call it a 51 screwdriver want to see 51 bits come out of this here we go you have to pack them in a very specific order in size so we have three there they have to be single sided double sided it will not fit they're like a millimeter longer this is a double-sided bit so that gives us a total of five the whee-ha adapter acts as a four millimeter hex wrench so that gives us six and then we have 44 in the main body because we have 15 double-sided bits and we have 14 single sided bits so how does it become 51 I'll show you we take one of these bits we stick it in reverse we stick the we high adapter and reverse and now we have a quarter inch allen wrench drive of course you don't have a lot of a lot of torque but if you had on for instance that double-sided long bit that would give you enough torque to use this as an allen wrench so 51 in one screwdriver world's smallest you
